Ap-p1icati0n fi1ed Aug'ust 27, "1925'. Serial No. 52,924.

This invention relates toplumbing appa:

ratus and especially to soil fittings.

One standard type t fitting consists of a combination Y and eighth turn bend having 011 its top end and on its lateral end what are termed hubs into which are inserted and packed and leaded ends of contiguous fittings. I V

In install ng the common Y and eighth cut into or through a girder on which the floor joists rest. One object of my invention is to eliminate'this injurious step.

"When a common bend of this type is used its top hub comes just below the floor planks and a short piece of tube called a stub is set in the top hub -and its lower.

end is packed and leaded tight. Thenpacked and leaded around the top end i of the 'stub which extends up into the flooring. A second object of my invention is to eliminate this separate stub and also the necessary packing and leading of it in the top of the Y hub, by extending up the .trunk of the Y to directly receive the ring and enable the latter tobe packed and leaded directly into the Y head.

The trunk of the Y usually stands vertical 1 3 and the lateral vent opening from it allows the sewage material to flow out laterally to the vent line. Therefore, another object of my invention is to provide a lip, which extends down to the bottom horizontal line 3 bend fitting it is frequently necessary to.

the usual flanged closetring is fitted and of the lateral vent of the bend and so out trunk while at the same time choking 0e latat the mouth of the branch.

hub, because .a stub (not shown) is 1 fitting.

In order to eliminate the stub and its necessary packing I extend the top end 5 of the trunk 2 up well above the. top of the lateral hub a so that the head or top of the if is in the floor opening.

Thispermits the hub 4 to lie betweenthe et into the topot the usualhead oi the Y 161l1l1i.) 4 under a floor 011 6 inch-joists it i tioor and girder without cutting awaythe 'la't'lei. Tlhe exterior of the head ofthe trunk is corrugated at 6 to help make'a tight joint with an applied ring. v

As clearly seen in the sectional view, a lip 8 extends down, atthemouth of the lateral. branch 3, to a pointlevel with the bottom of the eighth bend so that lateral surgi" g of sewage through the vent is prevented. To obtain ample vent area tot openingthe opposite sides of thevent branch are materially bulged at 9, as clearly seen in the top plan, Fig. 2. 3

Fronrthe above it will be seen that I have piovided means to prevent cutting a girder;

to eliminate a stub member. and its cost of labor and material for packing; and I arovide for stopping side escape-of sewage to ventand still provide ample air vent.
